A grassroots coalition of more than 70 organizations across the nation assembled by the #EdTaxCredit50 Coalition, my organization, supported this monumental reform.

The 529 reform will be able to expand quickly because there already are 13 million 529 college accounts today, with about $300 billion in total savings. More than 75 percent of these savings are held by families with $150,000 or less in income. As of January 1, withdrawals from these accounts and any new 529 accounts may be used to pay K-12 tuition.

While the 529 expansion is a great outcome in and of itself, it also helps lay the foundation for broader school choice victories in 2018. The 529 reform has several important features that can serve as a precedent for future action:

Applies to parents and students in all 50 states;

Doesn’t require any further state approvals or “opt in;”

Includes working-class and middle-class families, not solely the economically disadvantaged (in fact, no income threshold is applied at all, making it akin to economist Milton Friedman’s vision of universal parental choice); and

Imposes no new regulations on private schools or any infringements on religious liberty.

Each of these is a significant feature that naysayers — including many in the school choice movement — claimed could not be attained in the current political environment.

This partisan reality suggests that school choice advocates should take advantage of Republican control of the White House and both houses of Congress while it lasts.

What should still be done?

At the top of the list is a national tax credit to encourage charitable donations to nonprofit K-12 scholarship funds. For every dollar donated to a nonprofit scholarship fund, a taxpayer would reduce his tax burden by a dollar. The plan would inject charitable dollars into the hands of parents to make school choice and attaining a quality education a reality for millions of American children. This idea has the broadest grassroots support of any school choice idea. Presently, more than 240 organizations, including more than 40 labor unions, support a K-12 scholarship tax credit.

This idea could be improved by also encouraging charitable donations to apprenticeship and workforce preparation programs. This additional change would help close the “skills gap” that leaves millions unemployed at the same time that millions of jobs go unfilled.

Second, there is broad support for ensuring that the families of members of the U.S. military are afforded the broadest choice of public, private and religious schools for their children. Many military families are forced to send their children to inferior district schools near military bases without being given additional options. This simply is not acceptable given the sacrifices made by men and women in uniform and their families.
